software-development

Inspired by Dealing with personal failure,

I remembered my own failed software development experience. Finally I agreed to rewrite existing application. It took me less than a week to rewrite existing app and more up to 2 months to write from zero my own.

That 2 months were really hard and interesting. It was my first big software development process. I researched almost everything concerning to my application. Read Code Complete. Even some articles on how to create user interface. Some psychology stuff. Typography, Colors. DAL, DB Structure, SOA, Patterns, UML, Load testing etc.

I hope, that after a month or 2 I would get opportunity to continue working on my failed project, but before that, I would like to ask:

What are common mistakes in software development? What you shouldn't do in any case?
